2 Introduction Workswell WIRIS is the thermal imaging system for unmanned aerial vehicles (UAVs, drones). It is a lightweight all-in-one system equipped with a thermal imaging camera and a visible spectrum camera. The aim of the whole system is the simple transfer, storage and processing of radiometric (temperature) data directly from an unmanned aerial vehicle (drone) and displaying the data on the screen of the UAV remote controller in real time. The system also offers a variety of measurement functions, colour palettes or alarm (security) modes, which can be combined with a visible spectrum camera. Workswell WIRIS is designed in order to allow controlling all its functions during a flight. The system has eight digital inputs, which are fully compatible with standard RC receivers. Two inputs serve as navigation buttons in the menu, the rest are shortcuts for the selected functions (image capturing, video recording, palette switching, zoom and many others). The system supports a wireless video recording from a thermal imaging camera and a wireless image making from both, thermal imaging and visible spectrum camera. Data (video or individual images) can be saved directly using the UAV remote controller via the digital input ports on a control unit. The system offers a digital video output with 16:9 or 4:3 ratios. In 16:9 ratio, there is enough space for both live streams (thermal imaging camera stream and visible spectrum camera stream) on screen at one time. Workswell WIRIS connected to a standard FPV monitor (monitor not included)

16 16 Digital Inputs General Description The Workswell WIRIS system is equipped with 8 digital inputs. These inputs allow the user to control the system remotely via standard RC system or control unit of the UAV. First 2 digital inputs are fixed and serve as a navigation in system menu. These 2 inputs work in so called PWM mode, which means, that PWM input from standard RC receiver is expected. More information about PWM mode can be found in section PWM mode. The rest 6 digital inputs are fully customizable by user. These inputs can work in PWM mode or in trigger mode (see section Trigger mode). User can select the mode (PWM or Trigger) as well as function of each digital input via the system menu. Hardware compatibility Each digital input consists of 3 pins. These 3 pins are ground (GND), power supply (+/not required) and control signal (s). The Workswell WIRIS system comes with 2 servo cables that can be used for connecting the system to standard RC receiver. Note: Power supply is not required, GND and control signal are necessary.

17 17 PWM mode PWM mode is the default mode for each digital input. It means that PWM signal is expected on the input. PWM signal from standard RC receiver has the following parameters: Pulse length: 1 2 ms ( ms) Period: 20 ms (may vary for different receivers) In PWM mode 3 types of control elements are distinguished: 2 state element on/off switch, button ACTIVATED for pulse length > 1.5 ms DEACTIVATED for pulse length < 1.5 ms 3 state element - 3 state switch STATE 1 for pulse length < 1.25 ms STATE 2 for 1.25 ms < pulse length < 1.75 ms STATE 3 for pulse length > 1.75 ms Proportional element joystick, potentiometer LEVEL is current pulse length. Allows the user to control some functions proportionally. Note: Do not use higher voltage than 5 V.

44 44 Infrared camera behaviour Infrared camera warmup Modern infrared cameras are based on a sensor (microbolometer array) that needs to be warmed-up to the working temperature before it can be used. The sensor starts warming-up automatically when the user turns Workswell WIRIS system on. The infrared camera is usually ready in less than 5 minutes. During the warm-up process the accuracy of the measured temperature data is lower and various defects can appear in the thermal image. Therefore, we recommend to let the infrared camera warm before using it. Non-uniformity correction Infrared camera needs to be periodically calibrated in order to get reasonable measurement accuracy. This process is called Non-uniformity correction (NUC) and is done automatically. The user can set calibration period in ADVANCED MENU -> DISPLAY -> TIME TO CALIB. Time to next calibration is shown in STATUS BAR. It is recommended to use shorter periods (2 5 minutes) during camera warmup process and longer periods (10 30 minutes) when the camera is already warmed-up. Warning: Using only short periods (2 5 minutes) for a long time can cause early camera damage.

45 45 Maintanance Cleaning the WIRIS head and cables Liquids: Use one of these liquids: Warm water A weak detergent solution Equipment: A soft cloth Procedure: 1) Soak the cloth in the liquid. 2) Twist the cloth to remove excess liquid. 3) Clean the part with the cloth. Cleaning the infrared lens Liquids: Use one of these liquids: A commercial lens cleaning liquid with more than 30% isopropyl alcohol. 96% ethyl alcohol (C 2H 5OH) DEE (= ether = diethylether, C 4H 10O) 50% acetone (= dimethylketone, (CH 3) 2CO)) + 50% ethyl alcohol (by volume). This liquid prevents drying marks on the lens. Equipment: Cotton wool Procedure: 1) Soak the cotton wool in the liquid. 2) Twist the cotton wool to remove excess liquid. 3) Clean the lens one time only and discard the cotton wool. Warning: Make sure that you read all applicable MSDS (Material Safety Data Sheets) and warning labels on containers before you use a liquid: the liquids can be dangerous.
